Best ways to fuck over your mate whilst he's asleep. NSFW

So ye recently been doing my mate over whilst hes sleeping for my own pleasure, you know standard shit, human buckaroo, nandos sauce in the eyes. It's come to the point were it's getting a bit repetitive so I'm looking for some inspiration. Anyone got any good pranks? doesn't have to be whilst the targets asleep.

Here's an idea. Wait untill ur mate is lying on his back, put a sheet of paper on his chest, take a crap on the paper, set the paper's tips on fire with a lighter, wake him up with screams, watch him try to put out the fire.
If everything goes according to plan ur mate will be fucking scared and his arms will be covered with shit.

Kidnap everyone within a 20 mile radius of his house, and burn everything except his house within the exclusion zone, then somehow scorch the sky so it goes a red colour, leave just one burnt child on a swing. Teach a midget polar bear how to talk and get it to explain to him that they are the only 2 left on Earth and it is up to them to repopulate the planet. Then 50 years later, when hes on his death bed reveal to him it was a hoax, and that the Polar Bear was already pregnant before they met and that the 5 children he had fathered and cared for were not actually his.
